SP Scientific XE75 Temperature Cycling System FTS Air-Jet Sample Cooler/Heater D

Manufacturer: FTS Systems

Model: XE752

Condition: Used. This system is in Fair cosmetic condition.  There are lots of small scuffs/scratches/dings especially in the bigger cabinet that make it look a little rough from close up.  The place where the air input goes in the machine may be a little bent on the unit you receive, but this does not affect function. Cosmetic appearance may vary slightly from pictured unit(s).

Notes: This unit is in mostly-working condition.  It gets cold and hot, but the temperature transitions are longer than specified by the manufacturer.  Heating times are about twice as long as they should be.  Cooling times especially are slow, up to triple the rated 20 seconds from +125 to -55.  Also, stability at set point is not within specification, bouncing as much as several degrees + and -.  Fixing these issues may be as simple as re-tuning the PID values in the controller, but we are not sure.  The Air Flow and Refrigeration status lights do not illuminate.  No other testing was done. No manuals, cords/cables, or additional items are included if not listed or shown.
